Technical Summary
This vulnerability bypasses the Mark-of-the-Web (MoTW) feature, a security measure in Windows operating systems that flags files originating from the internet as potentially untrusted. MoTW is typically applied to files like downloaded documents, images, or executable files, which prompts a warning when opened. However, this vulnerability occurs when 7-Zip fails to properly propagate MoTW protections to files inside double-encapsulated archives.
An attacker can craft an archive containing another archive (a “double archive”), and 7-Zip did not properly propagate MoTW protections to the content to the inner archive.
This flaw allows any malicious content in the inner archive to be executed without triggering any security warnings. Consequently, this exposes Windows users to the risk of remote code execution and other malicious activities.
| CVE ID | System Affected | Vulnerability Details | Impact |
| CVE-2025-0411 | 7Zip Prior to v24.09 | This flaw allows attackers to execute arbitrary code through double-encapsulated archives that bypass MoTW protections. | Arbitrary remote code injection, potential system compromise |
